“…These main findings described above encourage research to develop new solvent formulations and blends that can improve the overall performance of the CO 2 capture process in terms of faster absorption kinetics, higher CO 2 absorption capacity, lower energy requirements for solvent regeneration and higher resistance to thermal and oxidative degradation [12][13][14][15].…”

Solvent degradation and volatile compound emissions are two of the major concerns about the deployment of carbon capture technologies based on chemical absorption. In this context, partial oxy-combustion might reduce the solvent degradation due to the use of a higher CO 2 concentrated flue gas. This work evaluates the oxidative degradation of a novel AMP/AEP blend, namely POS #1, under partial oxy-combustion conditions. The effects of temperature and flue gas composition were evaluated in terms of solvent loss, degradation rates, NH 3 emissions and degradation products. The experiments were set at temperatures up to 70 ˚C and two levels of O 2 concentration-3%v/v and 6%v/v. The CO 2 concentration of the flue gas ranged between 15%v/v and 60%v/v CO 2. The novel solvent POS#1 showed high resistance to degrade and resulted in lower degradation rates than MEA in all the operating conditions evaluated in this work. The maximum degradation of AEP and AMP was 24% and 19%, respectively. MEA degraded almost double under the same conditions. Temperature and O 2 concentration enhanced the oxidative degradation of POS #1. However, the use of higher CO 2 concentration in the flue gas led to lower degradation rates of AEP and AMP and hence oxidative degradation was partially inhibited under partial oxycombustion conditions. The presence of higher CO 2 content in the flue gas decreased the NH 3 production and a 70% reduction of its emissions was achieved as the CO 2 concentration shifted from 15%v/v to 60%v/v. Other major degradation compounds such as formate and 2,4-lutidine were also decreased. New degradation products were not identified so that the suggested degradation pathways proposed in the literature were not influenced by the presence of higher CO 2 concentrations.

“…Kang et al figured out that the 2-amine-2methyl-1-propanol solution regenerated with calcium chloride failed to be recycled to capture CO 2 , while calcium oxide could successfully regenerate the amines and increase cycling stability. 40 To decrease the cost of calcium sources, Ji et al regenerated amines with fly ash; 41 however, limited by the low content of calcium oxide, the desorption efficiency and working capacity with fly ash were not satisfactory. In addition, the mechanism between different amines and calcium oxide was still not clear.…”

An integrated absorption–mineralization process (IAM) was proposed to desorb and mineralize CO2 captured by amine solvents using the semidry desulfurization slag (DFS). Four typical amine solvents (monoethanolamine, diethanolamine, methyl-diethanolamine, and 2-amine-2-methyl-1-propanol) were investigated in the IAM process to evaluate the working capacity, recycling stability, and regeneration ability of the amine solvents. The reaction mechanism between CO2-saturated amine solutions and the DFS was interpreted with characterization by Fourier transform infrared spectroscopy and nuclear magnetic resonance. The results indicated that bicarbonates were more beneficial to CO2 chemical desorption than carbamates. Calcium hydroxide could mineralize bicarbonate and regenerate protonated amines, while calcium sulfate could only desorb bicarbonates and carbamates. By adjusting the solid–liquid ratio to prevent calcium from participating in mineralization, 2-amine-2-methyl-1-propanol showed the best recycling performance among all the amines because of its fast absorption rate, high CO2 desorption efficiency, and excellent stability.

“…Recently, many studies on mineral carbonation technology using Ca(OH) 2 have been reported. 31,32 Kang et al 31 reported that during CO 2 capture using adenosine monophosphate (AMP), mixing of Ca(OH) 2 instead of CaCl 2 showed superior performance in CO 2 desorption and sorbent regeneration. The Ca(OH) 2 employed in these studies is reagent grade.…”
